Summary: Memory leak in presence module

Initial Comment:
Version 1.3.2

Openser's SHM utilization continues to rise over time.  After a day or so run with 3500+ registered endpoints some of which are subscribing to various events, the load is removed from the server for a number of hours and with memory debuging turned on, openser is stopped.

The Memory status (SHM) contains many thousands of:

 alloc'd from hash.c: mem_copy_subs_noc(230) 

line 230 of modules/presence/hash.c:

dest->contact.s= (char*)shm_malloc(s->contact.len* sizeof(char));


Looking through the code, in modules/presence/subscribe.c around line 1461 I find:

shm_free(del_s);

shouldn't there be something like this before it?

if (del_s->contact.s) {
    shm_free(del_s->contact.s);
}
